- The author has long benchmarked vibe-coded app clones; this week Opus 5.5 few-shot a fully working Figma with 8 prompts in 3 hours and minimal guidance.
- Previous clones merely resembled the real thing; as a casual Figma user he can't spot the difference — and an LLM can even operate the app on the fly.
- The biggest jump is in UX understanding and attention to detail. He also built Google Meet, Docs, Telegram, and Linear with single prompts.
- Disclose: run on his startup Mana, which halves the code and adds primitives, but the leap is mostly model capability.
